Need Help with replacement window size Urgently

I have 5 windows i need to get replaced. All are on the second floor. The measurements for the replacement window sizes that i can fit in there are 24w x 45h but the closest windows i can find that are 9 inches shorter than what i need. How can i put replacement windows in when i have to make up the 9 inch gap in there? Im a renter and my landlord is a cheap @$$ and doesnt wanna pay an actual window company to replace them so and doesnt wanna pay a butt load for custom sized windows either. Is there anything i can do?

You do realize you will be liable for any windows you install? Water leaks, breakage at install, egress sized for bedrooms, etc....
